It is at this moment that the formation of spores occurs reproductive bodies that are destined to permit the algæ to traverse, without perishing, those phases where life is impossible.
The air supplied to him could be heated almost white-hot and then chilled before being introduced into the aseptic chamber for him to breath, if such a thing was desired. Or the air removed could be made incandescent so no possible germ or its spores could get out. Wastes removed would be destroyed by passage through a carbon arc after innumerable previous sterilizing processes.
It should be borne in mind, however, that we have to deal not only with the adult organisms, but with the spores also. The application of cold may keep the spores from developing, while heat may promote their development, and the course of the disease may vary, therefore, according to our choice of treatment.
A suppressed cry from Rae Melzer caused me to recollect the file and brush she had missed. "Just a second," raced on Kennedy. "On this file and brush I found spores of those deadly anaerobes dead, killed by heat and an antiseptic, perhaps a one-per-cent. solution of carbolic acid at blood heat, ninety-eight degrees dead, but nevertheless there.
Thus, the singular conclusion is forced upon us, that the greater and the smaller sacs of the "Better-Bed" and other coals, in which the primitive structure is well preserved, are simply the sporangia and spores of certain plants, many of which were closely allied to the existing club- mosses.
"Where's the sphere?" asked Masters. "He died of frustration or sorrow over having killed the wrong man," Taylor said grimly. Taylor indicated the half-formed monster in the pot. "Now we've got to get rid of that one and all the unhatched spores." "If that metal pot hatches 'em, we will," said Masters. "We'll dump the metal."
One problem, however, was left open, and that was why certain forms of the disease had their chills every fourth day and so were called quartan ague. This was quickly solved by the discovery of another form of the organism, which ripened its spores in three days instead of two.
The spore cloud drifted and eddied about them; rained down on their heads and half bare breasts, covered their garments and swiftly they began to change! Their features grew indistinct merged! The glistening white spores that covered them turned to a pale yellow, grew greenish, spread and swelled, darkened.
The spores of the living club-mosses contain so much resinous matter that they are now largely used in the making of fireworks, and upon the presence of this altered resinous matter in coal depends its capability of providing a good blazing coal.
D, E, F, and G represent mature plants belonging to the Gemiasma rubra. D represents a ripe plant, filled with spores, embryonic plants, and spermatia. E represents a ripe plant in the act of discharging its contents, it being about half emptied.
